[0035] It should also be understood that the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. As used in the specification of this application and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0036] It should be further understood that the term "and / or" used in the specification of this application and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0037] Material inspection usually refers to the process of regularly or irregularly inspecting and checking materials to ensure the safety, integrity, and usability of materials, including quantity verification, item inspection, etc. With the development of technology, more and more automated and intelligent tools are applied to material inspection. For example, by scanning labels on materials such as barcodes, QR codes, RFID, etc. with scanning devices for rapid data collection and processing, and then comparing them in real time with the records in the inventory management system to quickly obtain the inspection results.

[0038] However, existing scanning devices can usually only be used for labels on items at close range in a well-lit indoor environment. In a harsh warehouse environment, such as when the lighting is dim or the item is located at a high position or in a place that is difficult for the patrol personnel to approach, the scanning device lacks intuitive indication, making it difficult for the patrol personnel to determine whether the scanning device is correctly aligned with the item label, thus reducing the work efficiency of the patrol.

[0039] In view of the above problems, the present application provides a data acquisition device 100, which is applicable to a variety of patrol environments and can quickly locate the target label, improving the data acquisition efficiency and accuracy of the patrol personnel. Please refer to Figures 1 to 4 , the data acquisition device 100 includes a housing 110, a sensor 130 and an optical module 140. A visible window 120 is provided on the housing 110. The sensor 130 is located inside the housing 110 and is correspondingly arranged with the visible window 120. The sensor 130 senses the label on the item through the visible window 120 to collect data; the optical module 140 is used to indicate whether the sensor 130 is aligned with the label.

[0040] A data acquisition device 100 is provided, including a housing 110. An opening 120 is provided on the housing 110. A sensor 130 is provided inside the housing 110. The sensor 130 is correspondingly arranged with the opening 120. The sensor 130 senses the label on the item through the opening 120 to collect data; the data acquisition device further includes an optical module 140 for indicating whether the sensor 130 is aligned with the label.

[0041] In the data acquisition device 100, the light beam emitted by the lens of the optical module 140 irradiates the label on the item, namely the bar code, two-dimensional code or RFID tag storing the item data information, and the reflected light beam after irradiating the label is transmitted to the sensor 130. The sensor 130 reads the corresponding data information according to the label.

[0042] The sensor 130 is arranged inside the housing 110. The housing 110 is provided with a light-shielding structure with a visible window 120 only opened at one end, protecting the sensor 130 from being affected by external light beams and affecting the scanning and reading performance of the data acquisition device 100, and sealing the sensor 130 to prevent external dust or moisture from affecting the optical module 140 and the sensor 130.

[0043] Since the sensor 130 needs to be within the focusing range of the optical module 140 to sense and read the tag for data collection, when the data collection device fails to read the tag, the existing data collection device can only know that the tag cannot be read, but cannot prompt whether the distance between the data collection device and the tag is within the effective range. The operator does not know how to move the data collection device to successfully read the data information. In this case, the operator can only try multiple times to move the data collection device 100 closer to or farther away from the tag until it is prompted that the tag has been successfully read. This operation method is complex and cumbersome, reducing the work efficiency of the operator.

[0044] Therefore, in the embodiment of the present application, the optical module 140 is not only used to emit light beams and reflect light beams to the sensor 130 for the sensor 130 to read the data information corresponding to the tag, but also used to display light points or patterns on the tag to prompt the operator whether the tag is aligned. Especially for larger or inaccessible devices, such as tags on antennas, large power stations, or items on high shelves, the operator can intuitively judge whether the sensor 130 is correctly aligned with the tag according to the light points or patterns emitted by the optical module 140, enabling the operator to quickly align the tag to collect data and improving work efficiency.

[0045] In the embodiment of the present application, as Figures 1 to 4 shown, the data collection device further includes a reminder 170. The reminder 170 is communicatively connected to the sensor 130, and the reminder 170 is used to issue a prompt after the sensor 130 successfully collects data.

[0046] After the sensor 130 successfully collects data, once the data is verified as valid, the sensor 130 generates a status signal and sends the status signal to the reminder 170. The reminder 170 gives a prompt to the operator according to the received signal, such as sound, light, or vibration.

[0047] The connection between the sensor 130 and the reminder 170 can be achieved through a wired interface such as UART, SPI, I2C, etc. or a wireless communication module. In the present application, using a wired interface can ensure the stability, real-time performance, and anti-interference ability of the transmission of the status signal.

[0048] The reminder 170 in the embodiments of the present application can provide reminders through vibration, a prompt tone, or lighting. For example, when conducting material inspections in a computer room or other noisy environments, due to the high background noise, it may be difficult for operators to determine whether a scan is successful by hearing. In such cases, using the vibration or lighting reminder function can effectively notify the operator of the status of each scan, ensuring that they do not miss any successful scan detections. Similarly, in a dim or poorly lit environment, the operator may not be able to visually confirm whether the data acquisition device 100 has successfully read the tag data. At this time, vibration or sound reminders can be used as an auxiliary means to help the operator confirm that the data has been read, thus avoiding missed detections caused by lighting problems. This ensures that there are no missed materials during the material inspection process, improves the efficiency of the inspection work, and reduces repetitive work and work delays. The reminder method of the reminder can be adjusted according to the needs of the operator and environmental conditions.

[0049] Further, continuing as Figures 1 to 4 shown, the sensor 130 includes an image sensor 132 and a radio frequency sensor 131.

[0050] As Figure 4 shown, multiple sensors 130 are provided in the data acquisition device 100 to adapt to different tags. There are many types of tags that can store data information, such as barcodes, two-dimensional codes, and RFID electronic tags. A barcode is a pattern composed of black and white stripes along the horizontal direction, and different combinations of stripe thicknesses represent data information; a two-dimensional code can store data information in the planar space in both the horizontal and vertical directions; the image sensor 132 for reading barcodes and two-dimensional codes obtains data information by identifying, decoding, and reading the images presented by barcodes and two-dimensional codes.

[0051] The image sensor 132 in the embodiments of the present application can simultaneously identify two-dimensional codes and barcodes through the optical module 140 and has corresponding decoding rules, including but not limited to UPC, EAN, QR, etc. The general image sensor 132 can save costs, and the occupied space in the housing 110 is reduced, making the overall structure of the data acquisition device 100 lighter, smaller, easier to carry and hold, and convenient for the inspection personnel to operate.

[0052] The radio frequency sensor 131 is used when the tag on the target item is an RFID (Radio Frequency Identification) tag. The radio frequency sensor 131 emits radio wave signals. When one or more RFID tags enter the signal range, they will simultaneously send the stored data information to the radio frequency sensor 131, enabling multiple tags to be read at once, which is suitable for large-scale inventory of materials. The radio frequency sensor 131 in the embodiment of the present application can also be a UHF RFID (Ultra High Frequency Radio Frequency Identification) sensor 130, which can use radio waves to identify and track items and devices with RDIF tags at a relatively long distance, and it can work stably in a complex electromagnetic environment, making it more suitable for industrial scenarios such as the inspection of power materials during the power material inspection process.

[0053] The data acquisition device 100 in the embodiment of the present application can identify multiple types of tags on items to collect data information, adapt to various data acquisition requirements, and can be widely applied in multiple fields such as retail, logistics, medical, and industrial automation, improving the flexibility of use.

[0054] Continue to refer to Figure 1 , and there is also a button 150 on the housing 110. The button 150 is used to switch the operation of different sensors 130 according to different types of tags. As Figure 1 shown, there are multiple function buttons 150 on the housing 110, allowing the operator to flexibly select and switch the corresponding working mode of the sensor 130 according to the tag type on the target item. Each button 150 corresponds to a specific tag reading mode. For example, when a two-dimensional code is attached to the target item, the operator can press the button 150 corresponding to the image sensor 132. At this time, the image sensor 132 will start and begin to work. The image sensor 132 uses its high-resolution image capture ability to quickly identify and decode the two-dimensional code information.

[0055] If an RFID (Radio Frequency Identification) tag is attached to the target item, the operator can press the corresponding button 150 of the RFID sensor 130, and the RFID sensor 130 will immediately start and communicate with the tag through radio waves to read the RFID tag information.

[0056] Furthermore, the optical module 140 is located inside the housing 110. The optical module 140 is also used to provide a light source for the image sensor 132. The optical module 140 is exquisitely arranged inside the housing 110 to provide a stable and efficient light source for the image sensor 132. Moreover, it ensures that the image sensor 132 can obtain high-quality illumination under various environmental conditions, thereby improving the accuracy and speed of reading barcodes and two-dimensional codes.

[0057] In one embodiment of the present application, continue to refer to Figures 1 to 4 and in combination with Figure 5 , the optical module 140 includes a first optical module 141 and a second optical module 143. The first optical module 141 has a first focal length and is used to image on a label within the range of the first focal length; the second optical module 143 has a second focal length and is used to image on a label within the range of the second focal length; the focal length parameters of the first focal length and the second focal length are different.

[0058] The first optical module 141 and the second optical module 143 in the optical module of the data acquisition device 100 respectively have different focal length parameters to meet the imaging requirements of labels with different distances and sizes. The first optical module 141 uses an LED lens. As Figure 5 shown, the first light beam 142 emitted by the first optical module 141 is incoherent light. Since incoherent light can provide uniform illumination, it is suitable for imaging of labels at close range. And the cost of the LED lens is low and the durability is stronger. The first optical module 141 has a first focal length and is suitable for reading image labels such as barcodes or QR codes with smaller size, higher density or closer distance.

[0059] The second optical module 143 uses a laser lens, and the second light beam 144 emitted is coherent light. Due to the high directivity of coherent light, its divergence angle is small, and it can accurately irradiate the label on a distant object; due to the monochromaticity of coherent light, it is ensured that even at a long distance, the label image scanned by the data acquisition device 100 can be highly clear, improving the resolution.

[0060] The focusing ability of the laser lens is stronger, and it can form patterns and light spots on the label at a long distance to indicate the side of the housing 110 where the window 120 is provided for the operator to hold, that is, the sensor 130 is aligned for scanning and identifying the label. The cooperation between the second optical module 143 and the image sensor 132 is suitable for fast scanning in industrial automation and logistics systems.

[0061] By setting two optical modules with different focal length parameters, the data acquisition device 100 can cover a wide reading range from near to far. The operator can select the most suitable optical module to image and collect data on the label according to the specific position and characteristics of the target label.

[0062] In another embodiment of the present application, please refer to Figure 6 , the optical module includes a first optical module 141 and a second optical module 143, and the first light beam 142 emitted by the first optical module 141 and the second light beam 144 emitted by the second optical module 143 have a certain intersection range.

[0063] In the industrial field, especially when managing large-scale equipment such as power supplies like antennas, power generation stations, and power distribution equipment, challenges such as large equipment size, wide distribution, high risk of manual approach, and harsh outdoor environments are usually faced. These devices may be located in difficult-to-access areas such as high shelves, mountaintops, or depressions, which brings inconvenience to physical inventory and inspection tours.

[0064] In this application, by setting the light beams emitted by the first optical module 141 and the second optical module 143 in the data acquisition device 100 to intersect in space, it can be ensured that the data acquisition device 100 still has sufficient brightness and a clear focus at a long distance, increasing the emission power of the optical module, that is, the sensing tag 300 range of the data acquisition device 100, enabling it to sense and identify barcodes or two-dimensional codes on items at a farther distance.

[0065] This design can also enable the data acquisition device 100 to display light spots or patterns on the tag 300 within a certain intersection area as a visual prompt to help the operator align with the tag 300. For example, Figure 6 as shown. Figure 6 From left to right in the figure are the light source and the optical lens in the optical module. The solid line in the figure represents the first light beam 142, and the dashed line represents the second light beam 144. When the first light beam 142 and the second light beam 144 intersect in space, due to the matching of their fragrance and wavelength, the light intensity is superimposed within the intersection area, increasing the brightness of the intersection area of the two light beams and forming a clear focus, that is, a light spot or a pattern. The distance between the farthest intersection point of the first light beam 142 and the second light beam 144 and the optical lens can reach 15 meters. When the single first light beam 142 exceeds a certain focal length range, such as after 8m, the brightness of the displayed light spot will decrease, and the second light beam 144 will encounter a similar problem after exceeding its certain focal length range. In this way, it is not convenient to give a visual prompt to the operator, and it is difficult for the operator to move the data acquisition device 100 well to align with the target tag 300. By the intersection of the two light beams, the effective distance at which the optical module 140 can image on the tag 300 is increased to 15 meters, making the data acquisition device 100 of this application flexibly applicable to application scenarios of long-distance scanning, such as power material management, high-shelf access, and outdoor material inventory.

[0066] In the embodiment of this application, as Figure 1 and Figure 2, the data acquisition device 100 is also provided with a collision cushion 160, and the collision cushion 160 is disposed to cover the housing 110. There will be a certain gap in the internal space of the housing 110 of the data acquisition device 100. When the data acquisition device 100 is impacted or accidentally dropped by an operator's slippery hand, the internal components are likely to loosen and shift, resulting in the malfunction of the data acquisition device 100. The collision cushion 160 is disposed to cover the housing 110, which can absorb the impact force during collision, reduce the direct damage to the internal components, and play a buffering role. In addition, the collision cushion 160 can also be filled in the gap of the internal space of the housing 110, which can absorb the impact force while ensuring that the internal components will not loosen and shift.

[0067] Specifically, the housing 110 is usually composed of a detachable upper housing 110 and a lower housing 110 for easy maintenance. However, there will also be a certain gap at the connection between the upper housing 110 and the lower housing 110, and it is impossible to completely seal the core internal components of the data acquisition device 100 in the housing 110. Therefore, the collision cushion 160 is also disposed along the periphery of the housing 110 to cover the gap between the upper and lower housings 110, preventing external dust or moisture from easily entering the housing 110 and protecting the internal sensor 130, optical module and other electronic components from being damaged. Since the structure of the window 120 part of the data acquisition device 100 is relatively fragile, the collision cushion 160 can be thickened. The design of the collision cushion 160 not only improves the protection of the internal components of the data acquisition device 100, extends the service life of the device, but also enhances the durability and reliability, enabling the data acquisition device 100 to work stably in a more demanding environment.

[0068] According to another aspect of the present application, a transmission device is further provided, such as Figure 7 shown, which includes a data receiving device 210 and the data acquisition device 100 of any one of the above. The data receiving device 210 is communicatively connected to the data acquisition device 100; the data receiving device 210 is used to receive the data collected by the data acquisition device 100 and upload the data to the background data center.

[0069] The data receiving device 210 includes but is not limited to a smart phone, a personal computer, a digital assistant PDA, etc. The data acquisition device 100 is responsible for reading and collecting data through the sensor 130 and sending the collected data to the data receiving device 210. The data receiving device 210 is used to perform data processing on the received data, such as data encryption, data integration, data anomaly marking, etc., and upload the processed data to the server of the background data center for further data analysis and storage.

[0070] The data transmission device 200 of the present application is connected and interacts with data through the data acquisition device 100 and the data receiving device 210. The data receiving device 210 only accepts one data acquisition device 100 that is connected and paired with it.

[0071] As Figure 8 shown, a data receiving module 211 and a data uploading module 212 are provided in the data receiving device 210; the data receiving module 211 includes a BT (Bluetooth) module and an NFC module; the data uploading module 212 includes a Lora (Long Range Radio) module and a 4G-LTE (Fourth Generation Long Term Evolution) module. The data receiving device 210 is communicatively connected to the data acquisition device 100 through the BT module or the NFC module, and the data receiving device 210 can upload data to the background data center through the 4G-LTE or Lora module.

[0072] In the industrial field, many materials are state-owned materials, and the processing and transmission of their data need to ensure the privacy and security of state-owned material data. The data receiving device 210 further includes a preprocessing module 213. The preprocessing module 213 is used to perform preprocessing after the data receiving module 211 receives the material information data from the data acquisition device 100, classify the data, and distinguish whether the item corresponding to the material information data is personal material or state-owned material. If it is state-owned material, the sensitivity of national resource equipment is relatively high. When the data receiving device 210 uploads the data to the background data, it will upload through a network specially designed for national critical infrastructure and important resource equipment, abbreviated as a private network. The private network is physically isolated from the public network and has higher security and stability. After the data receiving device 210 uploads the data to the national background data center through the data uploading module, the data of state-owned materials will be further analyzed and reported by professionals. These analyses include the usage situation of the materials, maintenance requirements, and giving inspection or inventory reports. If it is public or personal material, the data receiving device 210 uploads the data to the background data center through the public network using network communication methods such as LAN, Lora, or 4G.

[0073] Furthermore, the wireless communication between the data acquisition device 100 and the data receiving device 210 to transmit data is crucial. The communication method can be one or more of the following methods. For example, Bluetooth communication connection is suitable for low-power and long-distance application scenarios; or Wi-Fi connection, which is suitable for fixed areas such as warehouses and office premises.

[0074] The data acquisition device 100 can also be connected to the data receiving device 210 through the NFC module. In the embodiment where one data receiving device 210 is communicatively connected to and only to one data acquisition device 100, the NFC (Near Field Communication) module can be used to pair one data acquisition device 100 with one data receiving device 210. The data acquisition device 100 can transmit the collected data to the data receiving device 210 through NFC, or can also be transmitted through the above other communication methods.

[0075] In a scenario where many personnel need to conduct inspections and inventory materials, each inspector will obtain a data transmission device 200. Usually, one data acquisition device 100 and one data receiving device 210 are taken out from a storage cabinet where multiple data acquisition devices 100 and data receiving devices 210 are placed, and the two devices are brought close to each other for pairing. After pairing, the paired data acquisition device 100 and data receiving device 210, that is, the data transmission device 200 of the present application, are carried to start inspections outdoors or within the area outside the storage cabinet. This method is efficient and simple, the pairing process is fast, and since each data receiving device 210 is only paired with one data acquisition device 100, the accuracy and consistency of the data can be ensured, and the problem of data confusion caused by the start of multiple inspection tasks can be avoided.

[0076] The above are only the preferred embodiments of the present application, and do not impose any form of limitation on the present application. The protection scope of the present application should be subject to the protection scope of the claims. Although the present application has been disclosed above with preferred embodiments, it is not intended to limit the present application. Any person skilled in the art, without departing from the technical solution scope of the present application, can make some modifications or decorations equivalent to equivalent changes using the above-disclosed technical content. However, any simple modification, equivalent change, and decoration made to the above embodiments based on the technical essence of the present application without departing from the technical solution content of the present application are all within the scope of the technical solution of the present application.
